For one or two semester courses in Introductory Biology targeting non- and mixed majors. The goal of this text is to provide an engaging and easy to use book with an innovative and interactive media program. It achieves a unique balance in emphasizing concepts without sacrificing scientific accuracy. The new MediaTutor, found at the end of each chapter, integrates the text and media by providing a brief description of the CD or WEB activity and the time requirement for completion. In creating the book and the media package, the authors and Prentice Hall reached out to the biology community - involving educators from around the country to help address the diverse needs of todays students. How do you engage your students and help make biology relevant to them? *NEW - Chapter-opening Case Studies and chapter-ending Case Studies Revisited - Includes Did Dinosaurs Die from Lack of Sunlight? from the chapter on Photosynthesis and Teaching an Old Grain New Tricks from the chapter on Biotechnology. Provides an innovative framework for students to learn and make connections between biological concepts and processes. *Earth Watch/Health Watch essays - Covers biodiversity, ozone depletion/pre
This volume brings together perspectives from scholars of different scientific backgrounds endeavouring to understand and debate the interactions and relationships between humans, nonhuman species and natural ecosystems in order to overcome the classic human/environment dichotomy. Through discussions informed by the humanities, arts, social and natural sciences, the book deals with the way different disciplines approach this relationship. These diverse perspectives are compared to enable a cross-cutting analysis of human/nature interface throughout history. Changes forced by the utilization of resources and habitats, as well as climate changes are analysed and discussed, enhancing the importance of a multifaceted approach for a better understanding of the complexity of both the human/world relationship and diverse interspecies connections and impacts.
The evolution of geological cartography in Cuba in its more than 135 years of history has been possible through the consultation of numerous archival reports, publications, maps and personal interviews with different authors and geologists of vast experience. A brief critical analysis is made of the increase in the degree of geological knowledge of the country since the elaboration of the Geological Sketch of the Cuban Island at a scale of 1: 2 000 000 (Fernández de Castro, 1883), first of Cuba and of Ibero-America, until the most recent Digital Geological Map of Cuba at scale 1: 100 000 (Pérez Aragón, 2016). Cuba and its surroundings are a geological mosaic in the southeast corner of the North American plate with rocks from many different origins, from Proterozoic to Quaternary, extended along the southern border of the plate. From the Eocene, this belt has been dissected by several great faults, related to the development of some great oceanic depressions (Cayman trough and Yucatan basin). The fossil record of Cuba, which covers approximately the last 200 million years of life on Earth, is rich in very varied fossils, witnessing a wide diversity of organisms, both animals and plants, that inhabited the Antillean and Caribbean region; and that constitute the inheritance of the biological diversity that the current Cuban archipelago exhibits. As a result of the preparation of the Cuban Metallogenic Map at scale 1: 250 000, forty-one models and eight sub-models of metallic mineral deposits were identified. These models, of descriptive–genetic type, together with the analysis of their spatial distribution and their relationship with geology, allowed the identification and mapping of ten mineral systems, linked to the geodynamic environments present in the Cuban territory. Cuba has large deposits of limestone, loam, dolomite, kaolin, gypsum and anhydrite, rock salt, marbles, sands and clays of different types, zeolites, peat, therapeutic peloids and many more. There are manifestations of decorative and precious rocks such as jasper, jadeite, different varieties of quartz and even xylopals. A compilation of geochemical data of oceanic basalt samples from previous works, together with data of analyzed samples during this study in order to discuss geochemical criteria based on immobile element (proxies for fractionation indices, alkalinity, mantle flow and subduction addition), provide a comprehensive ophiolite classification according to their tectonic setting. This book addresses different facets of the geological knowledge of Cuba: history of its cartography, marine geology, fossil record, stratigraphy, tectonics, classification of its ophiolites, quaternary deposits, metallogeny and minerageny.
La presente Versión 2000 es una nueva edición de la Historia general de México, preparada por el Centro de Estudios Históricos de El Colegio de México. En esta ocasión se incorporan, por primera vez desde la aparición original de la obra en 1976, varios cambios importantes, entre los que destacan la sustitución de algunos capítulos y la revisión y actualización de otros. Los capítulos sustituidos o renovados profundamente incluyen una amplia variedad de temas: las regiones de México, la prehistoria, el mundo mexica, el siglo XVI, el siglo XVIII, las primeras décadas del México independiente, la cultura mexicana del siglo XIX y la política y economía del México contemporáneo. Los capitulos correspondientes a estas temáticas han sido reescritos o modificados por autores que figuraban ya en la edición original: Bernardo García Martínez, José Luis Lorenzo, Pedro Carrasco, Enrique Florescano, Josefina Z. Vázquez, José Luis Martínez y Lorenzo Meyer.
¿En qué se basan los estudiosos del tema del fin del mundo para advertirnos y apurarnos a que tomemos precauciones? Los creyentes reconocemos que es posible el fin del mundo como lo conocemos porque las señales que la Biblia y los Mensajes Marianos dicen que lo anunciarán... ya las estamos viviendo. Otras culturas antiguas y videntes de todas las épocas también predijeron lo mismo y, sorprendentemente, se han venido realizando sus predicciones. Pero si Ud. es de los que no creen en nada de lo anterior, permítame decirle que, en la realidad actual, con estudios científicos y pruebas de ellos, se ha señalado que existen varias amenazas potenciales para la humanidad y que, de concretarse, efectivamente ACABARÍAN CON EL MUNDO COMO LO CONOCEMOS.
